Scenario #1
Swine Flu ManufacturerYou are an analytical chemist working in R&D for a large pharmaceutical company which is manufacturing a swine flu vaccine. The pressure to bring this product to market is intense. The first production batches have been made. But first you have to meet the product specifications.
Swine Flu SpecificationsColor ColorlessAppearance Free of visible
particulateAssay 5 mg/mL (HPLC)pH 7.4Heavy metals Less than 10 ppm
The product passes, except for color – the product has a slight yellow tinge
Disaster!QC sends it to you to figure it out
They require an answer within 24 hours
What would you do?Instrumentation available to you
Infrared spectrometer with ATRMass spectrometerNMR, 400 MHzXRFICP-OESFluorimeter
Considerations
What might be causing the color?What concentrations should you look for?Sample prep?
Scenario #2
Industrial Espionage!You have been hired to perform some clandestine analytical work.Your task: to determine the components of fireworks made in China so the product can be copied.You have several products to analyze; you need to determine the explosives, colorants and oxidizers.
What would you do?Instrumentation available to you
UV-visible spectrometerInfrared spectrometerRaman spectrometerGC/MSAtomic absorption
ConsiderationsWhat types of materials do you need to identify?Do you need quantitation?Safety
Scenario #3
Patent InfringementYour patent for a new drug to treat psittacosis has been challenged for infringement.The challenger believes the actual structure of your drug (an antibiotic) is not what the patent claims it is.You need to respond within 30 days.
What would you do?Instrumentation available to you
Fluorescence Mass specNMRInfraredICP-MSX-ray fluorescenceX-ray diffraction
ConsiderationsWhat aspects of the structure need to be proved?How close is close?Could sample prep affect structure?
Scenario #4
Product TamperingA consumer has returned a bottle of tablets that were purchased recently that are suspected of having been tampered with.Your job is to determine whether product tampering is likely.
Product TamperingThe product container
Outer box• Lot number, expiration date?• Any tears, signs of re-glue?
Bottle holding tablets• Has it been opened previously?• Number of tablets present?
The tabletsSize / shape / color?Markings?Composition?
What would you do?Instrumentation available to you
InfraredRamanICP-OESGC/MSNMR (60 MHz)X-ray diffraction
ConsiderationsSensitivity: How sensitive do you need to be to ensure that no adulteration has occurred?QuantitationComparison to a retain of good product
Scenario #5
Art AuthenticationIt was only a small garage sale, but you found a heavily damaged painting in a handsome frame. You buy it for the frame.Once you get it home and inspect it, the painting reminds you of a Van Gogh.Is it possible????
What Would You Do?Instrumentation available to you
InfraredRamanICP-OESGC/MSXRF
Art AuthenticationWhat can a chemist do to “authenticate” artwork?What components could you analyze?How do you get samples for analysis?Can you perform in situ analysis? Non-destructive analysis?How deeply into the painting should you go?Once you get the analysis, what do you do with it?
